CVE-2025-52513
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn issue was discovered in Samsung Mobile Processor Exynos 2400, 1580, 2500. A race condition in the HTS driver results in an out-of-bounds write, leading to a denial of service.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA race condition in the HTS driver of Samsung Exynos mobile processors (2400, 1580, 2500) allows an attacker to trigger an out-of-bounds write operation, causing denial of service. The vulnerability stems from improper synchronization in the driver code that handles hardware thread scheduling or sensor interactions.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the Exynos chipset modelCheck the device or system information to determine if an Exynos 2400, 1580, or 2500 processor is in use. On Linux-based systems, this may be found in /proc/cpuinfo, /sys/devices/soc0/soc_id, or through vendor-specific diagnostic tools.Affected if The chipset is confirmed to be a Samsung Exynos 2400, 1580, or 2500.
-
Locate the HTS driver in the systemSearch for the HTS (Hardware Thread Scheduler or sensor-related) driver module or firmware blob within the system's driver directory. On Android/Linux systems, check /sys/module/, /dev/, or vendor-specific driver paths for any driver component named 'hts' or associated with hardware thread scheduling.Affected if An HTS driver or firmware component is present and loaded for the identified Exynos chipset.
-
Verify the HTS driver is active or loadedCheck system logs (dmesg, logcat on Android) or driver status files to confirm the HTS driver is currently active, initialized, or handling hardware thread scheduling/sensor interactions.Affected if The HTS driver is currently loaded and operational in the system.
-
Review system logs for race condition indicatorsExamine kernel logs, system event logs, or driver-specific logs for any error messages, warnings, or crash reports that may indicate a race condition in the HTS driver (e.g., synchronization errors, out-of-bounds memory access, driver crashes).Affected if Logs contain error messages or crash reports associated with the HTS driver that suggest the race condition vulnerability is being triggered.
-
Check for available security patchesConsult Samsung's security bulletin or the device manufacturer's update information to determine if a firmware or security patch addressing CVE-2025-52513 has been released and applied.Affected if No vendor security patch for this CVE has been applied, leaving the firmware vulnerable.
A system is affected if it contains an Exynos 2400, 1580, or 2500 chipset with an active HTS driver and has not received a vendor-supplied patch for this specific vulnerability.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor-supplied firmware/security patches from Samsung for affected devices. Until patch availability, monitor for anomalous driver behavior that may indicate exploitation attempts.
